Transcript

00:00

Thank you We sneak and here's your smoke du jour

00:05

brought to you by the letter r which clearly stands

00:08

for linear correlation coefficient Because there's got to be an

00:13

r in there somewhere All right Linear correlation coefficient are

00:17

tanks Values in what range And hear the potential answers

00:21

All right what is our people Okay what do we

00:24

know about linear correlation Coefficient What we should know is

00:28

that the value of the coefficient can show us how

00:30

close the relationship is to a linear one that is

00:34

a positive Our means that as x increases so does

00:38

why while the negative art tells us that as x

00:41

increases why decreased Well since both could be the case

00:46

we must be able to have a mix of some

00:47

positive in some negative numbers which knots out option c

00:51

d and e the only decision now is whether coefficients

00:54

can be any real number or if they're limited to

00:58

being between one and negative one And because in all

01:01

our days we've never seen an r value higher than

01:04

one or lower than negative one Well we're going to

01:06

assume it's the latter but the answer is b that's

01:10

B is in light bulbs Hey if arkan do it 00:01:13.689 --> [endTime] can't be
